The Divided Self: An Existential Study in Sanity and Madness (Penguin Psychology)

The outsider, estranged from himself and society, cannot experience either himself or others as 'real'. He invents a false self and with it he confronts both the outside world and his own despair. The disintegration of his real self keeps pace with the growing unreality of his false self until, in the extremes of schizophrenic breakdown, the whole personality disintegrates.
